We use mechanism design in order to study efficient arrangements when the ability of agents to perform certain welfare-improving transactions is subject to random and unobservable shocks. We study implementation via a payment system that involves assigning balances to participants and optimally...

We use mechanism design to study efficient intertemporal payment arrangements when the ability of agents to perform certain welfare-improving transactions is subject to random and unobservable shocks. Efficiency is achieved via a payment system that assigns balances to participants, adjusts them...

We study economies where improving the quality of institutions - modeled as improving contract enforcement - requires resources, but enables trade that raises output by reducing the dispersion of marginal products of capital. We find that in this type of environment it is optimal to combine...
